Search Bug: I am forced to search in word order

Using 1Password X 1.7.3
When searching for an item, I must enter my search terms in the order they appear in the item's title, without skipping any words.
Example: I have an item called "HSBC US Debit Card"
These searches return the item:
hsbc
hsbc us
hsbc us debit
hsbc us debit card
These searches do not return the item:
debit hsbc
card hsbc
hsbc card
hsbc debit
My first search term can be anywhere in the item's title, that is, these searches work:
hsbc
us
debit
card
But any terms that follow that first term must match against the terms that follow the first one without skipping any; these searches work:
us debit card
debit card
card
And these do not:
hsbc debit
hsbc card
us card

If I were to guess what's going on, search indexing works like this:
for each word in the item's title: [hsbc, us, debit, card]

• index the word e.g. "hsbc"
• for the list of words that comes after this word: [us, debit, card]
  • index the word + each sublist of words e.g. "hsbc us", "hsbc us debit", "hsbc us debit card"

The behavior I want
I want to be able to search for terms in my item's title in any order: e.g.:
card debit
card hsbc
